How many offspring of a hermit crab survive to adulthood?

The survival rate of hermit crab offspring to adulthood is quite low, with estimates suggesting that only about 1 in 1,000 to 1 in 10,000 larvae reach maturity. This high mortality rate is due to various factors, including predation, environmental conditions, and the challenges of finding suitable shells. Additionally, hermit crabs have a complex life cycle that includes a larval stage spent in the ocean, which further impacts survival rates.
